Description

Suction valve
Technical field
The present invention relates to a kind of suction valve that is arranged in the pipeline and is used for stream material; Can close, regulate by means of this suction valve and flow and prevent flow starts back; Therefore; Suction valve comprises the movable locking device that places valve chamber and is used for its opposing side at valve chamber, and said locking device can move by means of the pressure of stream material through the piston portion or the cylinder part that said locking device are formed in clutch release slave cylinder.Valve is particularly suitable for as the suction valve that is used for screw compressor and rotor compressor, and this suction valve makes flow loss very little, and can regulate, and where necessary this suction valve is closed.When compressor shutdown, prevent backflow from compressor through closing suction valve.
Background technique
In the past people know wherein have a kind of from patent gazette 6,695,007 suction valve, wherein, the mobile valve that makes of medium is opened.When flow reduces, perhaps for example when the pumping action of compressor weakens, recline valve base surface and valve cuts out of the spring pulling shutoff device in the valve.In a kind of like this spring reset valve, always produce the big slightly pressure loss, because the valve shutoff device is opened through flowing.Even spring with regard to its reaction force very a little less than, also can produce the pressure loss.Therefore when sizable compressor is almost day and night worked,, in compressed-air actuated production, become remarkable consumption because their suction valve makes the operating efficiency that has degenerated a little.In addition, be difficult to suction valve is turned back to the neutral position near closed condition through the spring force adjusting, so that reach the release of pressure state of compressor.Therefore, release of pressure must carry out under the situation of cut-off valve, and compressor is worked simultaneously, and this situation perhaps takes place when increasing the resilience factor or the motion shutoff device reclines closing surface in addition.
Summary of the invention
For the shortcoming that overcomes appearance with regard to its flow loss, obtain a kind of very little suction valve that uses for compressor; And developed a kind of new suction valve that is used for stream material; This suction valve can be arranged in the pipeline; And its shutoff device pressure by means of stream material when piston or the cylinder part that shutoff device is formed in the clutch release slave cylinder can move, and this clutch release slave cylinder is through the pressure operation of stream material.Set forth above the invention is characterized in introduced the essential pressure of stream material in the said shutoff device through being contained in the inner bleeder of shutoff device.
Advantage of the present invention is valve not to be opened can in valve, be caused any flow loss.This valve both because its quality by means of gravity, stays open state again by means of the swabbing pressure of compressor, can impact in the direction that shutoff device is drawn to open position said pressure in the cylinder space that is formed by shutoff device.Compressor must a single pass bleeder with negative pressure-pumping in said space, and in the loss that does not after this take place about valve is opened.The pressure that the control utilization that is contained in the inner bleeder of the shutoff device of suction valve is directed to its medium carries out.Closing and open through the available medium that pressurizes of manipulation suction valve carried out.Therefore, control taking place has nothing to do with compressor operating.When cut-off valve was upwards installed about its inlet openings, shutoff device promoted opening of suction valve by means of the quality of himself.Shutoff device also can be adjusted to any neutral position between closed and opened position.When the pressure of the medium that shutoff device is pressed to closed position when bleeder is discharged rapidly to the pumping tube of compressor, can make the motion of shutoff device from the closed condition to the open mode very fast by means of bleeder.Suction valve is for causing the very little pressure loss through the mobile of it because make get into and go out the style of side make extraordinary streamlined be possible.
Description of drawings
The present invention is described with reference to the accompanying drawings, wherein,
Fig. 1 representes that valve of the present invention opens the sectional view of side.
Fig. 2 is illustrated in the valve in the closed position.
Fig. 3 is the connection diagram of valve.
Embodiment
Fig. 1 representes suction valve, and its shell is formed by two anastomosis part 1a and 1b, and this anastomosis part 1a and 1b can link with the bolt that passes hole 6 each other.The fixedly circular sleeve shape part 4 that is connected to the shutoff device on another part 1b by means of the wing plate 2 that strides across the circular flow channel guiding is fixed, and its outer surface is suitable for working with part 3 as slip surface.Part 3 and 4 is as cylinder that moves relative to each other and piston.Part 3 is equipped with filler 11, and under the situation of closing, nestles the apparent surface of part 1a, and filler 11 is compressed into closed state simultaneously.The wing plate 2 that part 4 is connected on the part 1b is thick slightly, might pass it thus passage 5 is introduced the part 4 from the outside.
Bleeder is fixed in the sleeve shape part 4 through threaded couplings 12.This bleeder has bleed hole (tap hole) 7, and this bleed hole 7 directly leads to the suction space of compressor.In addition, it comprises in the cylindrical frame 8 of valve motion closes flange 10, and this closes flange 10 is flexible materials, like polyurethane.Supporting lip 9 is connected on the framework 8.If close flange 10 back, along passage 5 and further along the pressure of 13 guiding greater than the pressure in bleed hole 7, then close flange 10 and close bleed hole 7.Pressure in the bleed hole 7 is shutoff device in internal control cylinder space 3 and part 4 also.Under the state described in Fig. 1, there is not pressure to be introduced to bleeder through passage 5.For example, passage 5 also can join on the pressure identical with compressor suction side, in other words, joins on the chamber that bleed hole 7 enters.Shutoff device 3 remains under the state shown in Figure 1, and does not attempt to become to close.Therefore, it is minimum that the flow loss that is caused by shutoff device reduces to.
The situation of Fig. 2 all can reach when compressor shutdown and work.For example, be directed, close flange 10 motions thus to close bleed hole 7 from the pilot pressure on the pressure side of compressor flange 10 back of closing at bleeder.Close the material yield of flange 10, therefore, pressure can get in the cylinder space via the crooked outward edge of flange 10, and with circulation in shutoff device 3, and pressure is shifted shutoff device 3 onto closed position.At this moment compressor release of pressure ground operation is perhaps shut down.Pressure can not leave compressor backward and discharge.
If want to make suction valve to open, then take place very soon, because the pilot pressure of passage 5 is drawn, this is an air very in a small amount.Then in the cylinder space; Come the pressure inside of self-closing device 3 can push the flange 10 of closing of shutoff device 3 to the left side a little immediately; Come the pressure inside of self-closing device 3 to enter in the suction space that starts compressor through bleed hole 7 rapidly thus, still keep in the position shown in the figure 1 and close flange 10.In shutoff device 3 inside, by the negative pressure rising of compressor suction, and shutoff device 3 can pass through valve to moving to open position and flowing rapidly.Therefore, the operation of compressor or its startup acceleration valve opens.In addition, the special position through suction valve of opening of valve is accelerated, if according to Fig. 1 and 2, shutoff device 3 moves downward open position under the effect of gravity thus.
By only the amount of being conditioned of medium being introduced in the space that forms between shutoff device 3 and the part 4, also might make shutoff device 3 in position, obtain to adjust the neutral position according to the quick bleeder of Fig. 2 through passage 5.
Fig. 3 representes the main schematic representation of valve.Valve 14 is suction valves, and it comprises the part 1a and 3 among Fig. 1 and 2.Valve 15 is bleeders, and it comprises the part 8,9 and 10 among Fig. 1 and 2.Valve 16 is control valves, through opening of this control valve pressure is guided to bleeder 15, and this closes suction valve 14, and the not operation of tube compressor 12.Pilot pressure reaches shutoff device 3 through bleeder and also this shutoff device is risen, and suction valve is closed.When removing the pressure control of valve 16, the low pressure or the suction of leading in the aspiration line 13 of compressor are removed pressure from the inside of shutoff device 3, and it is descended, and this situation is the open position of suction valve.Has reference character 17 from the pressure line of compressor 12 beginnings.The inlet openings of suction valve is marked by reference character 14 in schematic representation shown in Figure 3.From the pressure line 17 of compressor 13, can pilot pressure be taken in the valve 16.Also might obtain pilot pressure from some other external pressure source.
